Information About KL4004
The KL4004 is part of Beckhoff’s KL series of analog output bus terminals, designed for distributed signal generation in automation environments. It provides four independent channels with a voltage range of 0…10 V, offering precise control with a 12-bit resolution and an output error of less than ±0.1%. Each channel is short-circuit proof and ensures reliable signal generation for loads greater than 5 kΩ. Compact and easily installed on a DIN rail, the KL4004 integrates seamlessly into modular K-bus systems with no manual configuration required.
Key Features:
-
Four Analog Outputs: Supplies four independent voltage outputs within the 0…10 V range for versatile signal generation.
-
12-Bit Resolution: Provides fine signal gradation for accurate control in automation processes.
-
Short-Circuit Proof Design: Ensures output safety by protecting channels from electrical faults.
-
Fast Conversion Time: Updates outputs within ~2 ms for responsive system performance.
-
Low Output Error (< ±0.1%): Guarantees precise voltage output relative to the full-scale value.
-
Strong Electrical Isolation: 500 V isolation between K-bus and signal voltage ensures safe and interference-free operation.
-
Compact Modular Housing: Slim 12 mm profile saves space while delivering four output channels.
-
Seamless System Integration: Requires no addressing or configuration, working directly within Beckhoff’s K-bus architecture.
The KL4004 delivers the reliability and precision required for high-quality analog signal generation in distributed automation systems.
